One more tip, you might try using Meza[1], an automated MediaWiki install/deployment tool to get you up and running quickly. It comes pre-baked with several extensions[2] including visual editing and the extensions I mentioned above (WireTap & WatchAnalytics). It was actually created by a talented team at NASA and makes things much easier (including suggested extensions for enterprise use) if you have access to a server.
